Specialisations that make a difference
Every project demands a unique approach. These are the disciplines where our team adds the most value.
GEO — Generative Engine Optimization
AI engines like ChatGPT, Perplexity and Google AI Overviews are redefining how people find answers. Our GEO service makes sure your brand shows up as a cited source on these platforms. We combine citation data, entity optimization and authority content to position you where Google alone is no longer enough.
Technical SEO in depth
More than 200 checkpoints per audit: from crawl architecture to structured data implementation, covering Core Web Vitals, JavaScript rendering and crawl budget optimization. We work directly with your dev team so every technical fix lands cleanly and lasts.
International SEO — 14 native languages
We don't translate, we localize. Native writers in 14 languages, hreflang strategy, per-market URL architecture and local keyword research. From DACH to LATAM, every market gets content that sounds authentic and ranks organically.
